Plants consumed by non-human primates represent potential drug sources for human disease management. In this study, we isolated kaempferol-3-O-rhamnoside as an active compound from the leaves of Schima wallichii Korth., a plant commonly consumed by non-human primates. Its anti-cancer activities, including its ability to induce apoptotic mechanisms, were investigated in MCF-7 breast cancer cells. Results showed that in MCF-7 cells, kaempferol-3-O-rhamnoside inhibits cell proliferation in a dose-dependent manner and promotes apoptosis via the activation of the caspase signaling cascade, which includes caspase-9, caspase-3 and PARP. Our results provide a basis for further exploration of kaempferol-3-O-rhamnoside as an active compound for potential anti-cancer therapeutics.

Actively proliferating cancer cells require sufficient amount of NADH and NADPH for biogenesis and to protect cells from the detrimental effect of reactive oxygen species. As both normal and cancer cells share the same NAD biosynthetic and metabolic pathways, selectively lowering levels of NAD(H) and NADPH would be a promising strategy for cancer treatment. Targeting nicotinamide phosphoribosyltransferase (NAMPT), a rate limiting enzyme of the NAD salvage pathway, affects the NAD and NADPH pool. Similarly, lowering NADPH by mutant isocitrate dehydrogenase 1/2 (IDH1/2) which produces D-2-hydroxyglutarate (D-2HG), an oncometabolite that downregulates nicotinate phosphoribosyltransferase (NAPRT) via hypermethylation on the promoter region, results in epigenetic regulation. NADPH is used to generate D-2HG, and is also needed to protect dihydrofolate reductase, the target for methotrexate, from degradation. NAD and NADPH pools in various cancer types are regulated by several metabolic enzymes, including methylenetetrahydrofolate dehydrogenase, serine hydroxymethyltransferase, and aldehyde dehydrogenase. Thus, targeting NAD and NADPH synthesis under special circumstances is a novel approach to treat some cancers. This article provides the rationale for targeting the key enzymes that maintain the NAD/NADPH pool, and reviews preclinical studies of targeting these enzymes in cancers.

Introduction Diabetes mellitus is a chronic disease with a high prevalence world wide. This disease has also been reported to affect the quality of life (QOL) of the patient and their family due to its chronic nature and multi organ involvement. The aim of this study was to analyze the association between adherence to prescribed diabetes medication and diabetes-specific QOL in patients attending Secondary Health Care Facility in Bandung City, Indonesia. Methods A cross-sectional survey was conducted in the Secondary Health Care Facility in Bandung City, Indonesia. Data were collected between February and April 2014 using consecutive sampling. Adherence was assessed using the eight-item Morisky Medication Adherence Scale while diabetes-specific-QOL was assessed using the Diabetes 39 instrument. Results The results showed that among the patients, 49.4% exhibited low adherence, 29.7% exhibited medium adherence, and 20.9% exhibited high adherence to diabetes medication. Diabetes-specific QOL proved to be highly affected in the sexual functioning domain. Social-burden domain scores were better than overall QOL scores. There was a significant association between adherence and diabetes-specific QOL (p = 0.009) using The Kruskall-Wallis test of significance. The results of the post hoc Mann–Whitney tests (high vs medium adherence, p = 0.084; medium vs low adherence, p = 0.86; and high vs low adherence, p = 0.001) indicated that higher adherence to prescribed diabetes medication contributed to an improved QOL. Multiple regression analysis showed that the predictors of diabetes-specific QOL were adherence and patient income. Conclusions Adherence to prescribed medication showed a positive effect on diabetes-specific QOL in patients. Patients with a high adherence to medication had an improved QOL. This result is important not only in developing intervention programs for patients but also in improving their QOL through sustainable health promotion.

Background: The appropriate selection of empirical antibiotics based on the pattern of local antibiotic resistance can reduce the mortality rate and increase the rational use of antibiotics. Aims: We analyze the pattern of antibiotic use and the sensitivity patterns of antibiotics to support the rational use of antibiotics in patients with sepsis. Materials and Methods: A retrospective observational study was conducted in adult sepsis patient at one of Indonesian hospital during January-December 2011. Data were collected from the hospital medical record department. Descriptive analysis was used in the processing and interpretation of data. Results: A total of 76 patients were included as research subjects. Lung infection was the highest source of infection. In the 66.3% of clinical specimens that were culture positive for microbes, Klebsiella pneumoniae, Escherichia coli, Staphylococcus hominis were detected with the highest frequency. The six most frequently used antibiotics, levofloxacin, ceftazidime, ciprofloxacin, cefotaxime, ceftriaxone, and erythromycin, showed an average resistance above 50%. Conclusions: The high use of antibiotic with a high level resistance requires a policy to support its rational use. Local microbial pattern based on site infection and pattern of antibiotics sensitivity test can be used as supporting data to optimize appropriateness of empirical antibiotics therapy in sepsis patients.

The sarcopenic phenotype is characterized by a reduction of muscle mass, a shift in fiber‐type distribution, and reduced satellite cell regeneration. Sarcopenia is still a major challenge to healthy aging. Traditional Indonesian societies in Sulawesi island have been using nutmeg for maintaining health condition during aging. Interestingly, nutmeg has been known to stimulate peroxisome proliferator activated receptors γ (PPARγ) which may contribute to myogenesis process in cardiac muscle. There is limited information about the role of nutmeg extract into physiological health benefit during aging especially myogenesis process in skeletal muscle. In the present study, we want to explore the potential effect of nutmeg in preserving skeletal muscle mass of aging rats. Aging rats, 80 weeks old, were divided into two groups (control and nutmeg). Nutmeg extract was administered for 12 weeks by gavaging. After treatment, rats were anaesthesized, then soleus and gastrocnemius muscles were collected, weighted, frozen using liquid nitrogen, and stored at ‐80°C until use. We observed phenomenon that nutmeg increased a little but significant food consumption on week 12, but significant decrease in body weight on weeks 10 and 12 unexpectedly increased significantly in soleus muscle weight (p<0.05). Nutmeg extract increased significantly gene expression of myogenic differentiation (MyoD), paired box 7 (Pax7), myogenin, myosin heavy chain I (MHC I), and insulin‐like growth factor I (p<0.01) in soleus muscle. Furthermore, nutmeg increased serine/threonine kinase (AKT) protein levels and activation of mammalian target of rapamycin (mTOR), inhibited autophagy activity, and stimulated or at least preserved muscle mass during aging. Taken together, nutmeg extract may increase muscle mass or prevent decrease of muscle wasting in soleus muscle by partly stimulating myogenesis, regeneration process, and preserving muscle mass via IGF‐AKT‐mTOR pathway leading to inhibition of autophagy activity during aging. This finding may reveal the potential nutmeg benefits as alternative supplement for preserving skeletal muscle mass and preventing sarcopenia in elderly.

After the COVID-19 pandemic, telepharmacy has become increasingly widely used as an alternative to pharmaceutical care by remote pharmacists. Patients with diabetes mellitus are one of the patients who get benefit the most from telepharmacy practices, which allow patients to consult without meeting face to face and minimize the risk of virus transmission. The authors conduct an assessment of the benefits and limitations of using telepharmacy that are used throughout the world and then hopes that they can become a reference in the development of telepharmacy in the future. A total of 23 relevant articles were used for analysis in this narrative review after searching for articles in three sources, including PubMed, Google Scholar and ClinicalTrials.gov, until October 2022. This narrative review shows that telepharmacy plays an important role in improving clinical outcomes, patient therapy adherence and reduce the number of patient visit and hospitalization, but telepharmacy also has limitations in its use related to security and privacy, as well as pharmacist intervention that has not been maximized. However, telepharmacy has great potential to facilitate diabetes mellitus patients in pharmaceutical services.
